A community elevator and its intelligent control system

Abstract

The invention discloses a community elevator. The community elevator comprises an elevator body in an elevator shaft; the top of the elevator body is connected to a driving mechanism through a mooringrope; the lower part of the mooring rope is connected with a lifting mechanism; exhaust pipes are installed on the left side and right side of the interior of a top box body at the upper end of the inner cavity of the elevator body; exhaust fans are installed in the exhaust pipes; and a temperature sensor and a speed sensor are installed in the middle of the interior of the top box body. With thecommunity elevator of the invention adopted, the identity of a user of the community elevator can be determined, so that safety is improved; when the temperature sensor detects that the temperature of the inner cavity of the elevator body is too high, a PLC can control the exhaust fans to work, so that ventilation and cooling effects are achieved; after the mooring rope is broken, the speed sensor detects that the descending speed of the elevator body exceeds the preset speed, at the moment, an LED audible-visual alarm in a monitoring chamber gives an alarm, a first spring and a second springare arranged so as to enable a buffering effect on the elevator body after the elevator body descends, and therefore, hazards caused by the falling of the elevator body are reduced.

Description

technical field [0001] The invention belongs to the technical field of elevators, and in particular relates to an elevator in a residential area. The invention also relates to an intelligent control system for an elevator in a residential area. Background technique [0002] Elevator refers to the permanent transportation equipment that serves several specific floors in the building, and its car runs on at least two rigid rails that are perpendicular to the horizontal plane or at an inclination angle of less than 15° from the plumb line. The elevators in the existing community lack the identification of the user’s identity, which leads to poor safety. The exhaust fan of the elevator generally works all the time, which wastes electric energy. Usually, the permanent magnet synchronous traction machine is directly used to pull the elevator through the cable. The pulley guides and divides the force on the cable, so that the service life of the permanent magnet synchronous tractio...

Problems solved by technology

The elevators in the existing community lack the identification of the user’s identity, which leads to poor safety. The elevator exhaust fan generally works all the time, wasting electric energy. Usually, the permanent magnet synchronous traction machine is directly used to pull the elevator through the cable. The pulley guides and divides the force of the cable, so that the service life of the permanent magnet synchronous traction machine is short, and once the cable breaks, it cannot play a buffer role in the elevator's descent, nor can it play an alarm role. Therefore, we propose a Community elevator and its intelligent control system, to solve the problems mentioned in the above-mentioned background technology
